1、Designation: F1935 01 (Reapproved 2011)An American National StandardStandard Test Method forMeasuring the Headroom of a Backpacking orMountaineering Tent1This standard is issued under the fixed designation F1935; the number immediately following the designation indicates the year oforiginal adoption
2、 or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers tents for use in the sports ofbackpacking and mounta
3、ineering. It establishes requirementsfor the testing and marking of tents.1.2 This test method may contain test methods that do notentirely simulate real life situations. This test method isdesigned to give reproducible results in a laboratory andthereby a means for product comparison.1.3 This stand
4、ard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2. Terminology2.1 Definitions
5、 of Terms Specific to This Standard:2.1.1 tenta portable shelter made primarily of fabricweighing less than 3 oz/yd2, designed to be carried by theoccupants for while backpacking or mountaineering.2.1.2 usable headroomthe interior vertical measurementof a tent measured from the tent floor to the hig
6、h point on theceiling using a simple fixture that simulates an average usershead.3. Summary of Test Method3.1 The tent should be pitched on a flat surface in accor-dance with the companys supplied pitching instructions .3.2 The fixture shall be placed inside the tent. The ball israised until it come
7、s into contact with the ceiling, wall, poles,or any other obstructions inside the tent.3.3 The tape measure will now be hanging directly belowthe ball. The headroom measurement will be where themeasuring tape hits the tent floor. If the tent does not have afloor, record the measurement to the surfac
8、e the tent has beenset up on.4. Significance and Use4.1 This test method can be used to quantify and compareheadroom of backpacking and mountaineering tents. Themeasured headroom can be used as a manufacturing standardor a measurement that can be used by consumers to comparethe interior height of a
9、variety of tents, or both.5. Apparatus5.1 Specifications for Headroom Measurement Fixture (seeFig. 1):5.1.1 Styrofoam ball 6 inches in diameter (mean width ofmale head = 6.1 in.).25.1.2 Tape Measure,14 in. GraduationsThe tape ismounted into the bottom of the Styrofoam ball, and the first 6inches are
10、 removed from the tape. In this way, the reading willbe simple and accurate.6. Conditioning6.1 Tests may be completed under ambient conditions. Incases of dispute, test samples shall be conditioned in accor-dance with 6.2.6.2 The tent samples are first erected and dried in anatmosphere with a relati
11、ve humidity of less than 10 % for aminimum period of 24 h. They are then placed in an atmo-sphere of 50 6 5 % relative humidity, 20 6 2 C for aminimum period of 72 h. Tests may then be done outside theconditioning room, but the temperature shall be 23 6 5Candthe tests shall begin within 5 min. of re
12、moval from condition-ing and be completed within 4 h.1This test method is under the jurisdiction of ASTM Committee F08 on SportsEquipment and Facilities and is the direct responsibility of Subcommittee F08.22 onCamping Softgoods.Current edition approved April 1, 2011.
